One day an old gentleman was walking through the park. He saw a group of children standing near a tree. There was a cat in the tree. The gentleman came to the tree and asked what they were doing. One of the boys told him that they were having a competition. "We are telling lies," said the boy. "And the one who tells the biggest lie will keep the cat." The gentleman thought it was a good chance to teach the children a lesson. He told them that their competition was unusual. And then he said, "You know, I have never told a lie in my life." All at once the children began to laugh and they shouted, "The cat is yours, sir."
